The GUI wallet is closed source.
The coin (without GUI wallet) has been forked like 30 times already, starting back in April last year when the community started to figure out what a joke this launch was.
Hi BCN community,
I am investigating Smooth as a developer who spends his entire day attacking his competitors, with 50 posts attacking 3 competitors today. I am not here to assess the validity of any particular coin and I have never invested in BCN or know much about it apart from it was the original Cryptonote coin.
Feel free to vote or provide any info on Smooth that might be relevant.
